Rookie Needs Helpp

[Weezard]

I want to add more light during flowering. Is that ok to do?

Extra light during on-time? :thumbsup:


Extra hours of light?

No simple answer.
Some strains can do 13/11 and stay in flower once it has begun.
Some strains need more than 12 hrs of darkness to finish well.
Also the nature and intensity of your light will affect the amount of dark time required. Just not as much as the genetics will.

Do you know the preferences of the Black Domina?

@Dexter;
Good answer!
Over-fert is consistent with the symptoms.
It screws up the PH and the plant can't feed.
